has anyone installed their home made ccv kit under the hood instead of installing along the frame under the truck? i live in a very cold climate and i am concerned about those vent hoses freezing and creating excessive back pressure.

When I made my own CCV mod I mounted it on the frame and it gets COLD here in the winter but what I did was use 3/8" copper tubing to run along the CCV lines going to and coming from the CCV filter canister plus wrapped it around the canister itself then I insulated it with that foam pipe insulation that you can buy for your home plumbing then I ran the coolant from my coolant filter piping through this copper tubing. The CCV mod stays nice and hot so there is no worry of some condensation collecting in the bottom of it freezing and plugging it off. It's more work but I don't like just running a hose to the ground like some gys do.

found the thread i was talking about. you could mount the canister in the engine compartment to catch the oil where it should stay fairly warm and just vent it back to the intake. here read it for yourself i thought it was good infoMy $25 CCV Mod! Easy!

If you make the entire run slightly downhill, the tube will never choke up. I've had mine over a year and it got into the teens here last winter, never had one bit of trouble. You will see some steam from condensate burning off, but no concerns.

if your worried about dust just put a breather filter on the end of the line then you will definitely have some filtration if any air is going in and all the oil will just leak out the filter media if it accumulates enough. I know some of the 6.4's seem to have barely any noticeable collection in their canisters so a lot of guys have just vented to air and a breather would give you that peace of mind for keeping the dust out.
